To allwhom it may concern: *Beit known that I, 1 Claims SINGELYN,

a'citizen of the-United States, residing at Detroit, county-of Wayne,State of M1ch1- gan'yha-ve invented agcertain-new and use- :Eu'lImprovement in Automatic Air-Regulators for Automobile Gas En'gines, andde- I cla'r'e the following to -be'a"'-full', 'clear, and exactdescription ofthe same, such as w1ll .enable others skilledin the; arttowhich it pertains to make and use the same,"-reference" whic bein ,:.hadto the accompanying drawings; l1 form a part' of this specificatlonl 1My invention relates' to 1 an improvement r for: gas engines -for'niotor vehicles f Y The; object r :to: provide means whereby anadditionalsupply of'riair :will Be -admitted to the 'gas mixture 'as';thrunning speed ofi (r W n the? engine increases; .An additional obj ecmeans whereby the quantity I of; air this a'dmitted- V will ivary:directlyf as 'Zthe': speed-increases and such=addit1onalisupply willbe. automatically shuts ofli as the amount of fuel passingthrough vtheintake falls 'be lowzi-aucertainminrmummii an additional obj ecteisaloe-provide inexpensive s imple means connected up w1th=' the throttlerod so that actuation thereof to increase, the duel supply; Wlllautomatically furnish an additional air supply to the'e'n-.

In the drawings:

Figure l is a conventional gas engine with my improvement attached.

Fig. 2 is a detail sectional View.

A form of conventional gas engine is represented by a, the gas intakepipe is represented by b, accelerator rod 0 is connected up by means oflink d to bell crank e at the lower extremity of the throttle rod. findicates a plunger guide, having an interior air passageway p whichcommunicates with the atmosphere through air inlet holes 6. Plungerguide f is screwed or otherwlse inserted through the wall of the gasintake pipe, the interior air passageway 39 communicating with the gasintake pipe. Within the plunger guide is disposed a plunger 9 heldtherein by means of a spring k, so as to normally cover air inlet holes2'. A flexible linkage is provided connecting said plunger with theaccelerator rod. A telescopic link is here shown consisting of a rod isheld telescopically within tubular member j. A stop 9 is provided on theplunger, a stop 7' is promada nag-mention FOR v1 XUTILOMOBILE GAS-1i|11'GIl\TES.

' videdonthe telescopiclink. When the accelerator rod has been withdrawnsu'fiiciently to bring link 7' asit'pivots about its pivotal I point-onplunger g into perpendicular position thereto stop j is brought intocong and further rotation of tact with stop the-link about'itsipivotalpoint on'the plunger is prevented; Plunger "g is thenwithdrawn equally with the accelerator rod.

Forexample', let the position m indicate the-throttle valve as closed,The plunger is held'seated in the plunger guide and the 1 air inl'etholes are closed thereby. n would indicate the =positionof'the Llink jup to the time the acceleratorrod had been actuated such d-istance' thatit would begin to actuate the plunger and would be adjusted in such amanner a's to provide sufiicient inlet of gas tozth'egeng1ne"to"attain"-a predetermined engine speedi Passing point n or afterthis predetermined engine speed h'asbeen passed,

thev plunger :will -be actuated equally with theiaccelerator roduncovering air inlet holes in proportion to its actuation, therebyadmrtting ain, to ithesintake in proportion to' I the! increase of gasfldw thereinzl It will be 7 apparent 'thatithe withdra'wal of theplungerand consequent uncovering of air inletholes in theplungerwillbear a direct ratio to the admissiOn-of-fuehto the engine as regulatedby the-operation of thethrottle" rod It will-be observed that rodc'would be actuated by the accelerator pedal the same as through link (1connecting the same up to the throttle rod. The primary purpose howeveris to provide means whereby as the flow of fuel to the en ine isincreased after the passing of sai minimum rate of flow has beenreached, additional air supply would be automatically admitted to thegas mixture proportionate therewith and this would normally beaccomplished through the throttle rod.

What I claim is:

1. In a gas engine for motor vehicles, in

combination with the gas inlet pipe a plunger guide having an airpassageway leading therein such air passageway communicating with theatmosphere by means of a series of air inlet holes, a plunger disposedin said plunger guide normally closing said air inlet holes, meansconnecting said plunger with the throttle rod, such means so adaptedthat after the throttle rod has been actuated a predetermined distancethe plunger will commence to withdraw, uncovering the air inlet holes inthe plunger guide directproportion to the further actuation of saidthrottle rod beyond SIIChzPIGdGtQIIDiHGd'diS- tance.

2. In a gas -engine-for motorvehicles, the combination with an intakepipe, of a plungemguide'fittedtherein, such plunger guide being providedwith an interior air pas sageway leading to the intake pipe andconimunicating with the E atmosphere by g neans of air inlet-openings, aplunger disposed injsaid Plung u de a te ign; 1 spr g 1 m y holding saidplunger seated vin the plunger guide closing the air inlet openings,a-,tele-. scopie :lihkleminecting pivotally ,with said plungerl and ,theaccelerator rod, a ,stop' on nlet; openi g fii vd said plunger a stopon; said link adapted to coaot iththe stop onthe-,.p1l1nger whe thelinl; heenactuated a predetermined dista ngelby the n oyement oftheaccelenator d-e se? to sivi u raw ,t e i'plim q' y ith h elxeter 31:95miter th is me far-i rit res in .suchgperpendiculan ,PQSilZiOil, :means1 connecting v(the g acceleratore-rqd. with? the :2 throttle rod so the?sa-me may: be actuated: 1
